 This sounds like a bug in the persistent object library,
 what makes you think it is a bug in libstdc++?

 I have written a string class that replaces the allocator
 and it works for me.  You can see what I did by checking out
 module libcwd from cvs and looking at the file private_allocator.h
 and private_internal_string.h.
 
 My first thought is that you have forgotten to define
 a rebind<> member template.
 
 For info on how to obtain libcwd from cvs, see
